corpus u´teri that part of the uterus above the isthmus and below the orifices of the fallopian tubes.

cor·pus cal·lo·sum

[TA]

the great commissural plate of nerve fibers interconnecting the cortical hemispheres (with the exception of most of the temporal lobes, which are interconnected by the anterior commissure). Lying at the floor of the longitudinal fissure, and covered on each side by the cingulate gyrus, it is arched from behind forward and is thicker at each extremity (splenium [TA] and genu [TA]) but thinner in its long central portion (truncus [TA]); it curves back underneath itself at the genu to form the rostrum [TA] of the corpus callosum.

corpus callosum

The arched bridge of nervous tissue that connects the two cerebral hemispheres, allowing communication between the right and left sides of the brain.

corpus callosum

[kôr′pəs kalō′səm]

1 a transverse band of nerve fibers joining the cerebral hemispheres. It is located at the bottom of the longitudinal fissure between the two hemispheres and is covered by the cingulate gyrus.

2 the largest commissure of the brain, connecting the cerebral hemispheres.

Corpus callosum

cor·pus cal·lo·sum

(kōr'pŭs ka-lō'sŭm) [TA]

The great commissural plate of nerve fibers interconnecting the cortical hemispheres (with the exception of most of the temporal lobes, which are interconnected by the anterior commissure). Lying at the floor of the longitudinal fissure, and covered on each side by the cingulate gyrus, it is arched from behind forward and is thick at each extremity (splenium and genu) but thinner in its long central portion (truncus); it curves back underneath itself at the genu to form the rostrum of the corpus callosum.

corpus callosum

The wide curved band of nerve fibres (white matter) that connects the two cerebral hemispheres.

corpus callosum

a band of nervous tissue connecting the cerebral hemispheres in the higher mammals.

corpus callosum

cor·pus cal·lo·sum

The great commissural plate of nerve fibers interconnecting the cortical hemispheres.

corpus callosum (kor´pəs kəlō´səm),

n the largest commissure of the brain connecting the cerebral hemispheres.

corpus

pl. corpora [L.] body.

accessory corpus lutea

the corpora lutea which develop during early pregnancy in the mare and which follow the subsidence of the first corpus luteum.

corpus albicans, corpora albicantia

white fibrous tissue that replaces the regressing corpus luteum in the ovary in the latter half of pregnancy.

corpus amygdaloideum

a small mass of subcortical gray matter within the tip of the temporal lobe, anterior to the temporal horn of the lateral ventricle of the brain; it is part of the limbic system.

corpus amylacea

small hyaline masses of degenerate cells found in the prostate, thyroid, neuroglia and milk where they may be sufficient in a cow to block the teat sinus. They are formed by stasis of milk flow in a duct and inspissation of the fluids. Subsequently they may become detached and find their way to the teat.

corpus atreticum

scar in the ovary produced by atresia of a follicle when late in its development.

corpus callosum

an arched mass of white matter in the depths of the longitudinal fissure of the brain, and made up of transverse fibers connecting the cerebral hemispheres.

corpus callosum agenesis

all or part of the corpus may be absent and there may be additional associated defects.

corpus cavernosum clitoridis

one of the pair of erectile bodies of the clitoris.

corpus cavernosum penis

either of the two columns of erectile tissue forming the body of the penis or clitoris. See also corpus cavernosum penis.

corpus cavernosum penis rupture

common in bulls occurring during mating; commonly at the distal bend of the sigmoid flexure; result in hematoma and subsequent adhesions with inability to protrude the penis properly or angulation of the penis.

a progesterone-secreting yellow glandular mass in the ovary formed from the wall of an ovarian follicle that has matured and discharged its ovum. See also ovulation. In most animals that do not conceive the corpus luteum regresses quickly and a new follicle develops. The corpus luteum may be retained when there is uterine pathology which mimics pregnancy; no new follicle develops and the cow fails to come into heat. Called also retained corpus luteum. A similar clinical picture is observed with cystic corpora lutea.

MRI is also the best method for identifying intracranial anomalies associated with meningoencephalocele: holoprosencephaly, DandyWalker malformation, aqueductal stenosis, agenesis of the corpus callosum, and other midline abnormalities.
